Description

Technical Field

[0001] The utility model relates to the field of electric energy meters, in particular to an anti-electricity theft integrated electric energy meter shell. Background Art

[0002] An energy meter is an instrument used to measure electrical energy. Also known as a watt-hour meter, heat meter, or kilowatt-hour meter, it refers to an instrument that measures various electrical quantities. When using an energy meter, please note that under low voltage (no more than 500 volts) and low current (tens of amperes), the meter can be connected directly to the circuit for measurement. Under high voltage or high current conditions, the meter cannot be connected directly to the circuit and must be used in conjunction with a voltage transformer or current transformer.

[0003] Energy meters are typically installed within a meter box. However, the door structure of a typical meter box is relatively simple. Criminals can easily pry open the door with a crowbar to steal electricity, causing losses to legitimate users. Therefore, preventing the door from being pried open for electricity theft is a key issue that needs to be addressed in the design of an integrated anti-theft meter case. Utility Model Content

[0024] On the basis of conforming to the common sense in this field, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0025] The positive progress effect of this utility model is:

[0026] 1. By clamping the limit block in the clamping slot, the locking rod is restricted to prevent the locking rod from being separated from the clamping slot.

[0027] 2. When the anti-pry block is pried with a crowbar, the balls on the inclined surface of the anti-pry block will roll during the prying, making it difficult for the crowbar to apply force. In addition, when the anti-pry block is acted upon by the force of the crowbar, the anti-pry block will slide toward the first sliding groove under the force. When the spring is compressed, the anti-pry block will retract into the first sliding groove, leaving the crowbar with nowhere to apply force. Therefore, it is difficult to apply force when the crowbar is prying, thereby preventing the shielding cover from being pried open, thereby avoiding the possibility of electricity theft.

Therefore, it is difficult to apply force when the crowbar is prying, so that the shielding cover 2 cannot be pried open, thereby preventing the possibility of electricity theft;

[0056] After the crowbar is removed, the spring 1 402 will push the anti-pry block 401 to pop out. When the maintenance worker needs to open the energy meter housing 1, he can use the key 10 to insert the key 10 into the plug slot 3 904 until it reaches the rotation slot 903.
